The sector with a radius of 10 cm and a central angle of 216 ° is rolled into a conical funnel. The height of the funnel is known to be 8 cm, and the volume of the funnel is calculated

The sector with a radius of 10 cm and a central angle of 216 ° is rolled into a conical funnel. The height of the funnel is known to be 8 cm, and the volume of the funnel is calculated

Using the arc length formula, we can get l = 216 π R / 18O to get the arc length, and then we can get the bottom radius from the arc length L = 2 π R, R, h, then its volume is:
V-cone = 1 / 3 π r2h
